What is a JOZ file?
Java OpenStreetMap is a free OpenStreetMap map (OSM file) editor available for Windows, macOS, and Linux. It allows users to download or import OSM maps, mark them up with tagged nodes and paths, and submit their edits to the official OpenStreetMap project.
While editing maps, users can save their current Java OpenStreetMap session as a JOZ file. This allows them to re-open and continue editing that session in the future. JOZ files are ZIP archives that contain:
- A JOS file, which is an XML file that describes a session's layers, viewport settings, and version
- One or more OSM files, stored in sub-directories that correspond to the session's layers
How to open a JOZ file
You can open a JOZ file with Java OpenStreetMap (JOSM), to view and edit the session it contains:
- In JOSM, select File → Open....
- Navigate to and open your JOZ file.
If you want to extract the OSM files and other data a JOZ file contains, you can do so by:
- Renaming the file to use the .ZIP extension.
- Opening it as you would any ZIP file.
